Eimeria sp. is one of the most important parasites that cause very high economic loss in
poultry farms in Egypt. It causes a disease called coccidiosis. This study aimed to detect the
prevalence of Eimeria species in chicken and detection of its pathological effect within the
intestinal mucosa. The present study investigate the prevalence of Eimeria sp. in chicken
through fecal examination and the diagnosis was based on direct fecal sample examination
(unstained wet mount technique) and concentration techniques, followed by sporulation of
unsporulated oocyst for identification of Eimeria spp. and finally studying the pathological
effect of this parasite in the intestinal mucosa of infected chicken. The total prevalence rate of
Eimeria spp. was (66%). The incidence rate in Broiler chickens was (70%) and in Balady was
(58%). The highest percent of infection was at the age of (15-30) day (54.3% in Broiler and
72.4% for Balady), and the disease was more prevalent in winter than in summer. The species
that were detected are E.acovullina (the highest prevalence rate) followed by E.tenella,
E.necatrix followed by E.mitis (lowest prevelance rate). These results indicate that the
coccidiosis is a serious parasitic disease that effect on the poultry production in Egypt and
control measures should be put in consideration to overcome this disease.
